End Group Modification on Benzodithiophene as New π-Conjugated Donor-Acceptor Polymer for Organic Solar Cells |
| 초록 |
Two benzodithiophene (BDT) based π-conjugated donor-acceptor polymers (P-Cl and P-B-Cl) with out and with endgoup modification were synthesized and studied as donor polymer for OPV. The two BDT based polymers were synthesized one with benzene endgroup on pentyl side chain (P-B-Cl) and the other one without benzene on pentyl side chain (P-Cl) showed great contrast in their photophysical properties. P-B-Cl exhibited good absorption profile ranging from 300-750 nm with energy bandgap (Egopt ) of 1.86 eV, HOMO and LUMO of -5.565 and -3.705, respectively compared to P-Cl with Egopt of 1.85 eV, HOMO and LUMO of -5.525 and -3.675, respectively. Organic solar cell(OSC)s fabricated with P-B-Cl as donor and IT-4F as acceptor displayed an improved power conversion efficiency (PCE) of 11.1% compared to P-Cl with PCE of 6.3%. These results clearly emphasize that the endgroup modifications on side chain has a great ability for enhancing efficiency. |
